The business casual dress code is the most common office dress code in America, and because it’s so simple, it’s also easy to fall into a style rut. The good news is, upgrading your business casual attire can be done without spending a fortune, as it all takes is working with what you already have in your closet and pairing it with a few extras to give your office wardrobe some life.

Here are a few ideas on what you can do to upgrade your business casual style.

If you own a black blazer and matching trousers, upgrade your look by not pairing it with a white top. This combination is the vanilla of business casual wear, and there are so many ways that you can do better. First, choose a blouse in a print or color, and wear shoes with a matching or complementary shade. Accessorize with a dramatic necklace and a nice leather bag.

If you have a white button-down shirt, wear a black crewneck sweater over it. Pull out the cuffs of your shirt and fold it up. Pair this with dark gray trousers, red pumps, and a statement necklace.

Black slim cut trousers and a printed black and white blouse can be jazzed up with a wine colored blazer. Blazers in cobalt blue, marigold, and emerald green will work too. To mix it up, forego the black pumps and wear heeled oxford shoes instead.

A slim-cut chambray shirt can be tucked into a knee-length, circle or knife-pleated skirt for added appeal. Accessorize with a statement necklace, a silver man’s watch, nude pumps and a structured bag for a professional look.

A black pencil skirt can be livened up with a peplum top in a solid color or a small print. Make sure that the top has sleeves so you don’t have to wear a jacket to cover it up, as the peplum detail is the highlight of your outfit. Pair this with black or nude pumps and carry a matching handbag.

A bright-colored crewneck sweater, such as a hot pink piece, can be worn with gray or navy trousers. Accessorize with gray or navy pointed flats, a necklace, and a silver watch.
